Pretty new at this game, still.

For the first time ever, I discovered an access key. I flew over to a structure and found a secure container.

Flew near to the container, got the message: "Transmitting key... access successful."

And then the container failed to open. Just sat there, closed, with about four containers inside that I could never get to.

Later in that mission, I used another access card to get into a secure colonial base successfully, so I know it's not a glitch with access cards in themselves.

Anyone else ever had this happen?
